How to add an Adblock Plus Filter Subscription:
Open ADP Options (Tools > Add-Ons > Adblock Plus > Options or right click on ADP status icon > Preferences)
Filters > Add filter subscription
Add a different subscription
Enter a title and this url:http://update.firenico.com/abp/nico.supersizeme.txt
This will bring FireNICO back up to speed and should improve the the overall experience.
